Dr. Gordon H. Clark was not a full preterist and I sincerely doubt that he would have agreed with anything C. H. Dodd had to say since Clark called Dodd a theological liberal. Here's a quote from Clark's book, The Holy Spirit, (Jefferson: Trinity Foundation, 1993). After saying that miracles only occur in certain periods of biblical history, Clark says:
"There will be, however, a fourth period when miracles will occur again. As the great tribulation of the last twenty centuries approaches its close, for 'we must through much tribulation enter into the Kingdom of God,' the apostasy of the denominations will grow worse and worse, and the man of sin, who resides in a city on seven hills, will be revealed before the day of Christ. Then shall the Lord Jesus be revealed from heaven, in flaming fire taking vengeance on them that know not God and obey not the Gospel of our Lord Jesus Christ. Pentecostalism is one step into this apostasy." The Holy Spirit, page 97.
The full preterist view is based on asserting the consequence, a logical fallacy. It goes like this:
If P then Q. Q therefore P.
So to fill in the information for the symbols in the syllogism. If P (the Bible says Jesus would return soon), therefore Q (Christ has already returned in A.D. 70). Q (Christ already returned in A.D.), therefore P (the Bible says Christ has already returned). Notice the second P is slightly modified and so is Q. But that is the basic argument of the full preterists. As you can see, it is illogical and a fallacious argument that assumes the consequent from another assumption, namely that because Christ would return soon P, then He has already returned. But does soon always mean imminent? Obviously not. As someone else has already pointed out, a day with the Lord is as a thousand years. Two thousand years is nothing in God's scheme of things.
. . . knowing this first: that scoffers will come in the last days, walking according to their own lusts, 4 and saying, "Where is the promise of His coming? For since the fathers fell asleep, all things continue as they were from the beginning of creation." 5 For this they willfully forget: that by the word of God the heavens were of old, and the earth standing out of water and in the water, 6 by which the world that then existed perished, being flooded with water. 7 But the heavens and the earth which are now preserved by the same word, are reserved for fire until the day of judgment and perdition of ungodly men. 8 But, beloved, do not forget this one thing, that with the Lord one day is as a thousand years, and a thousand years as one day. 9 The Lord is not slack concerning His promise, as some count slackness, but is longsuffering toward us, not willing that any should perish but that all should come to repentance. 10 But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up. (2 Peter 3:3-10 NKJV)
Full preterists are scoffers who ask those of us who believe the Bible's admonition to watch, "Where is the sign of His coming?" Of course, the answer is He has not come yet. But He will and when He does return what will He find you doing? (Luke 18:1; Mark 13:35; Luke 12:37-38). That's the question, isn't it?
